Thefpresent nvention'relates. to a locking and particularly relates to a locking device which may be generally applied hoods, and so forth,

Beyond the ring 'i9 theshank has a continua.- tion or stem 20 which is-'provided withopeninga 2|. to receive the ends 22 of the bow shaped rel silient member 23. the b ow also extending through an lopening 2l inv said stem 20. I

The bow element or wingshaped element '23 .is preferably made of a resilientwire, which is-firmly held in said stem 2l by the openings 2l and 2l.

l"The resilient latch 'i3 consists of a bowed plate 26 to the'rear plate. il, the

In operation, the locking d/evice maybe locked in Figures 1 to 4 by turn 35 ing (the key i2 ninety degrees from its lposition 3 shown and then inserting the spring bow 23 linto the key slot 30, the stem '20- tting into the er1- larged central portion 3l 'of said key slot 30 (see alsoFl'gure). 1-4

It will be noted that the inside plate Il is offset at 34 so that its offset portion 35 may rest in lthe back of the plate il and permit the outside portionsof two platesV l0 and il to be flush being lbest shown in F18- ure 3.

.Itis thus apparent that'the present application has provided a simple, inexpensive and reado5 ily manipulated locking-.device of general application to automobile constructions or to other .usesandwhichisotparticularvalueinplaces `.where a durable. inexpensive and strong'locking `clrmstrixction.is desired It win be ncdtmt the key element n may llsne turned in either direction` to .lock the device and that the resiliency of the plate Il together with the snap d the element 2l into'the recess 21 will giveailrm connection which will not tend' to loosengwith rattling orshaking of the device tofwhich the lock is-applied.
